Problems solved by technology

This type of steel is developed on the basis of low-alloy high-strength weldable steel. They are generally quenched and tempered directly after rolling, or strengthened by controlled rolling and controlled cooling processes, which can save energy and have low content of alloying elements. , the price is cheaper, but the hardness is high, wear-resistant, and the process performance is acceptable. Due to these advantages, this type of wear-resistant steel plate is very popular among users.

Abstract

The invention discloses a high-carbon steel multi-alloy wear-resisting ball and a production method thereof. The wear-resisting ball comprises the main chemical compositions in percentage by weight: 1.0-1.2% of C, 1.2-1.6% of Si, 1.6-2.2 % of Mn, less than or equal to 0.05% of P, less than or equal to 0.25% of S, 1.5-2.5% of Cr, 0.2-0.3% of Mo, 0.005-0.01% of B, 0.025-0.05% of Ti, 0.08-0.15% of V and the balance of Fe. The production method comprises the steps of melting stock, modifying twice, pouring, quenching, tempering and obtaining finished products. The grinding ball produced with the production method of the invention has high hardness, high wear resistance, high toughness and high impact resistance; the production method of the grinding ball is easy and simple to operate.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a high-carbon steel multi-alloy wear-resistant ball and a production method thereof. Background technique [0002] Ball mill is widely used in cement, mining, thermal power, building materials and other industries. Grinding ball is the most commonly used grinding body in ball mill, which consumes the most in use. With the development of industry, various large-scale ball mills are increasing year by year, and the consumption of grinding balls is also increasing significantly. This not only consumes a large amount of iron and steel materials, but also a large amount of iron powder enters the boiler, which corrodes the boiler parts and reduces its service life. Therefore, continuous research to improve the wear resistance of grinding balls and reduce their unit loss has important economic significance. [0003] The general term for steel materials with strong wear resistance (what), wea...
